Would it be possible to get the above effect while using alphas from a model+texture? I ask because our cloud system works like so:
We create a cylinder object that rotates in a selected direction ( slowly ).
To get the desired cloud effect we apply a texture to it using SRGB and Alpha layer to remove the areas we do not want to cover by clouds.
Our desire is to use the dome ( which encases the cylinder and the world ) where we apply the sun and generate the GPU gems lighting ( god rays ) from the clouds that are showing. I guess the question is, is there any way to create the same desired effect by using the Cloud system we have in place?
